Ingress
Configure Quality of Service (QoS) for packets entering the device. Ingress denotes packets
arriving into the 6381 from a WAN or LAN interface. The mappings are converted to CoS.
QoS can be configured on a per interface basis. Select the interface — USB, Ethernet, Bridge —
which needs to be configured.
Ingress Untrusted Mode
Untrusted is the default Ingress page setting for all interfaces. In this mode, no domain mapping
is honoured in the RG. All packets are treated as CoS6 (best effort)
Untrusted
The default Ingress page setting. No domain mapping is honoured. All packets are
treated as CoS6, the best effort priority.
Layer2
Enables you to map an incoming packet with layer 2 (MAC addresses and bridging,
rather than by IP address and routing) with VLAN segregation for priority. Only
configurable on WAN interfaces.
Layer3
Enables you to map type of service (ToS) bits of incoming packets from the IP
network to CoS for each WAN/LAN interface.
Static
Enables you to configure a static CoS for all packets received on a WAN or LAN
interface.
To configure QoS on ingress:
1.
From the navigation bar at the top of the screen click
Advanced
2.
From the left hand navigation pane select
Ingress
.
3.
On the
Ingress
page, select the interface from the
Interface
drop down.
4.
Select the appropriate
Untrusted
,
Layer2
,
Layer3
, or
Static
radio button.
5.
Click

Ingress Layer 2 Configuration
Layer 2 page enables you to map an incoming packet with VLAN priority to CoS. This feature is
only configurable on the WAN interfaces as VLAN is only supported on the WAN side in the
current software release.
Interface
Select the WAN interface here to configure the CoS for incoming traffic. Only
WAN interface can be selected as VLAN is currently supported only on the WAN
side.
Class of Service
The selections are (in the order of descending priority): CoS1, CoS2, CoS3,
CoS4, CoS5, and CoS6.
User Priority
The selections are 0, 1, 2, 3, 4, 5, 6, 7.
To configure Ingress Layer 2 to CoS:
1.
From
Interface
drop-down box, select PPPoE to configure QoS on this WAN interface.
2.
Select
CoS1
in
Class of Service
and
5
in
Priority Bits
.
Any packets with priority marking 5 is mapped to CoS1, the highest priority that is normally
given to the voice packets.
3.
Click
Apply
to temporarily activate the settings.
4.
Select
CoS2
in the
Class of Service
field and
1
in the
Priority Bits
field.
Any packets that have priority bits of 1 are mapped to CoS2, which is the second highest
priority. This is given to the high priority packets such as video.
5.
Click
Apply
to temporarily activate the settings.

The changes take effect when you click Apply; however, if the RG configuration is not saved,
these changes will be lost upon RG reboot.
6.
Repeat step 2-5 to add more rules to PPPoE1.
Up to eight rules can be configured for each interface.
Any priority bits that have not been mapped to a CoS default to CoS6, the lowest priority.
7.
Repeat step 1-6 to create rules to another WAN interface.
Any WAN interface that is not configured has the default Untrusted mode.

Ingress Layer 3 Configuration
The Layer 3 page allows you to map ToS bits of incoming packets from the IP network to CoS for
each WAN/LAN interface.
Interface
For both WAN and LAN interfaces, you can configure QoS for layer 3 (IP) data
traffic.
Class of Service
This CoS field allows you to map incoming layer 3 WAN/LAN packets to one of
the following CoS (in the order of descending priority): CoS1, CoS2, CoS3,
CoS4, CoS5, and CoS6.
ToS
The type of service field takes values from 0 to 255.
Default Non IP
A static CoS can be assigned to all layer 3 incoming packets (per interface) that
do not have an IP header, such as PPP control packets and ARP packets. The
default is CoS1 (recommended).
To configure Ingress Layer 3 to CoS:
1.
From
Interface
drop-down box, select
LAN Group 1
to configure QoS on this interface.
2.
Select
CoS1
in
Class of Service
and enter
22
in Type of Service (
ToS
).
Page 99 / 131
6381-A4 Router Users Guide

Any incoming packet from LAN Group 1 (layer 3) with a ToS of 22 is mapped to CoS1, the
highest priority, which is normally given to the voice packets.
3.
Leave the default value CoS1 in Default Non-IP.
Any incoming packet from LAN Group 1 without an IP is mapped to CoS1, the highest
priority.
4.
Click
Apply
to temporarily activate the settings.
The changes take effect when you click
Apply
; however, if the RG configuration is not
saved, these changes will be lost upon RG reboot.
5.
Repeat step 2-4 to add more rules to LAN Group 1.
Up to 255 rules can be configured for each interface.
Any ToS that have not been mapped to a CoS is treated as CoS6, the lowest priority.
6.
Repeat step 1-5 to create rules to another WAN/LAN interface.
Any WAN/LAN interface that is not configured has the default Untrusted mode.
7.
To make the change permanent, click
Tools
and select
System Commands
. On the
System Commands
page, click

Ingress Static Configuration
The Ingress - Static page enables you to configure a static CoS for all packets received on a
WAN or LAN interface.
To configure Ingress static QoS settings:
1.
At the
Interface
drop-down box, select
Ethernet
.
Page 100 / 131

You are configuring QoS on this interface only. Any WAN/LAN interface that is not
configured has the default Untrusted mode.
2.
Select
CoS1
in
Class of Service
.
All incoming traffic from the Ethernet interface receives CoS1, the highest priority.
3.
Click
Apply
to temporarily activate the settings.
The changes take effect when you click Apply; however, if the RG configuration is not saved,
these changes will be lost upon RG reboot.

Ingress Payload Database Configuration
The Policy Database Configuration page enables you to configure QoS payload database and
policy routing.
QoS can be configured in the Ingress and Egress pages on a per interface basis. The Policy
Database page enables you to classify packets on the basis of various fields in the packet.
The following fields can be configured for QoS:
•
CoS
•
Source IP address/mask
•
Destination IP address/mask
•
Protocol
•
Source port start
•
Source port end
•
Destination port start
•
